. To all vwhom. it may concern.'

Be it known that IyAmL L. HANSEN,

. who was a subject of the King of Denmark, 1 but who have madeV application for Anticrivcan citizenship., but not yet completed thc formalities of becoming an American citi- .-,zen, residing at Chicago, in the county of Cook and State of Illinois, have invented a V' -z certain new and useful improvement in Un- `.loading Devices for Trucks and the like, of

, which the following is av specification.

It is generally recognized that owing to lzthe' heavy cost of running and maintaining 'motor trucks and the like, their elhciency and economy depends in a very large degree lon keeping them always in usetul operation,

the lowest possible minimum.

.and it is therefore imperative that the time spent in loading and unloading be kept to In handling coal. stone and the like it is quite easy to lill the. body or hopper on a truck through any of the Well-known means.

The problem, however, is to empty the hopper with equal speed, and a great many make-shifts have been employed. One method which has met with some degree of popularity is to mount the hopper on a frame so that it can-be bodily raised above the truck frame and the material run oil through a. spout. Another way is to raise one end of the hopper and tip the material through the other end. A number oi other Ways have been tried, but found. unsatisfactory in that they require a lange amount of power. According to my invention l propose to do away with any moving or tippingor raising of the hopper, Vbut will dump the ho per easily and rapidly and will still be able to have the hopper rigidly attached to the trame.

My invention is illustrated diagrammatically in the accompanying drawings, Where- 1n- Figure l is a detail side elevation of a truck With parts in section and parts omitted; Fig. 2 is a detail plan view of a truck With parts omitted; Fig. 3 is a detail section through the bottom of the hopper shoiving the bottom in open position; Fig'. 4 is' a diagrammatic detail longitudinal section through the bottom showing the interaction of the bottom members; side elevation of a modiiied form: Fig. (i is a detail side eleyation of a further modified form.

A is a truck frame.

Fig. 5 is a detail 1 .if is a rear supporting and driving wheel haring an axle A;I which supports the trncl: in any usual manner not shown.

E' B' are supports rigidly attached and projecting from the frame A.

C is a hopper having upper vertical Walls and lower and inwardly inclined Walls and an open bottom. l

D is a sliding gate provided with a rack l)l and adapted to be moved by the pinion l)2 in engagement with the rack and actu ated by the hand Wheel D3 to open or close the vopening D* in the rear panel of the inclined Wall.

E E are angle frames reinforcing the longer edges ot' the inclined hopper Walls.

Q .1 lul, lag la are spacing and track forming members respectively.

The bottom of the hopper is 'made up of the three slidably mounted panels F, Ffand F2 which are locatee in the space as indi cated in Fig. el. The panels F and F1 are provided at either end with downwardly projecting members F3, F4, F5 and F". The panels l"l and F2 are provided each at one end `with the'projecting lugs F", F8, projecting upwardly into the pathof the members haal, l"d and F respectively. The panel l2 is provided with the outwardly projecting iiangesl10 F which overlie the frame las and project outwardly on either side bevond it. The sprocket chainsG G ride orer the idler sprocket wheels G1 G1 and driving sprocket wheels G2 G2 which are inountel on the shaft (la which carries the gear G4 m mesh with the pinion GG, actuated by the hand Awheels (li. The flanges Ff are attached to the chains G on either side oi the hopper.

r[he conveyor ll travels on the supportingl rolls ll1 beneath the bottom of the hop, per and passes over the head roller H2 mounted on the. shaft lla and driven by yhead roller K1 driven 'from the engine in identically the. same manner as Shown in Fig. l. The belt also travels over the rollers K3 K' on the slidmg frame K5 which sliding frame is :adapted to be forced in or out by means of 'the pinion' K in mesh with the rack K7. The belt leads from the roller K* to the roller K8 on the frame A.

V It will be obvious that the operator by moving the slidable frame out will move the pulley K3 Vfarther away from the pulley-l or roller and bring the pulley K* closer to the fixed roller KS, thus extending the conveyer and causing it to project out from the rear of the truck.

It Will be evident that while Ihave shown in my drawings an operative device, still many changes might be made in size, shape and arrangement of parts without departing materially from the spirit of my invention,

and I v. ish therefore, that my drawingsbe `.5 Iegm'ded asin a eenseb diagremmatic. i

having a hopper body thereon of a conveyer mounted on the truck and adapted to receive the material from the hopper body and dis- 35 charge it fromthe truck, a horizontal sliding bottom door for'the hopper and means 1 for progressively opening said door in a direction` opposed to the feeding direction of the hopper bottom immediately above the conveyor and means for opening said door, and `a. connection between the motor and the conveyor whereby the conveyer may be driven therefrom.

3. The combination with a motor truck having a hopper body thereon of a conveyer mounted on the truck and Iadapted to receive they material from the hopperrv of the conveyer, :1 door in the rear side wall 40 body and discharge it from the truck, a 5'7* horizontal sliding bottom door for the hop@ per and means for progressively opening said door in adirection opposed to the feeding direction of the conveyer, and a con-v inection between the motor and the conveyer whereby the. conveyer may be driven theref from.
